How an Acoustic pulse recognition touch screens works?
APR touch screens work by analyzing the sound an object makes when it hits the glass through four piezos, and compares them to a pre-recorded table with millions of values.

Some Requirements For Touch Screen Computers?
Matte finishes on touch screen computers produce less glare and avoid the show of fingerprints on the more glossy screens. Some of these computers are also stylus-oriented and not all are multi-touch screens. Multi-touch allows easier manipulation of photos. With handwriting recognition, the feel of the stylus becomes important. It is best when the stylus feels like a pen or pencil. The computer should have its own video card and a lot of RAM memory.

When were touch screen cameras invented?
Touch screens have been used for many years in various applications. The first use of touch screens in cameras was seen as soon as touch screens were made sufficiently small to fit them to compact still and video cameras. They were seen in mass produced models from 2001 onwards and have become very common ever since.

How do touch screens work?
There are two main technologies for touch screens these days: resistive and capacitive. Resistive touch screens work by pressing a sheet of plastic against a conductive material underneath and recording the position at which this occurred. Capacitive touch screens work by having a layer that stores electrical charge on top of a sheet of glass, and recording when some of the energy from the glass is transferred to the user. Touch Screens work by having a thin overlay on top of the actual display. This overlay is a sensitive layer which transmits an electrical signal. The computing components then use this data to identify where the user has touched on the screen.
How does an touch screen work?
Touch screens can use many different methods for determining where on the screen it is being touched. The most common method, usually found on low-end touch screens, is a thin layer of plastic that contains miniature sensors that respond to an object touching it like a stylus or finger. The more advanced touch screens could use infrared transmitters and detectors to determine screen coordinates. In the case of the iPhone and iPod Touch, as well as other multi-touch devices, there is what's called a capacitance touch screen. These touch screens detect the minute electrical impulses produced by your body, and a combination of hardware and software translates the positioning of your fingers to control the application. In these types of touch screens, your finger must be used to control the device.
